There aren't a lot of people calling me by nickname now Before people used to call me NamKoo instead of my full name. Probably it's because calling by full name was inconvenient. But recently as I became the main male lead in the drama, in the news I saw NAMJOO in front of my name. I felt it's funny. In Korean character, Nam also means male, Joo also mean main. Thus they also say main male lead as NAMJOO, which is the same as NJH's name
